ACETYLENE-GAS GENERATOR.

Specification of Letters Patent.

, Patented ot. 2,1906.

Application filed March 9, 1906- Serial No. 305,127.

To all whom it may concern.-

[- bell 6 is mounted in the generator 1.

The

Be it known that I, JAooB W. WOODSON, a water which is placed in thegenerator 1 citizen of the United States, residing at Fort Worth, in thecounty of Tarrant and State of Texas, have invented a new and ImprovedAcetylene-Gas Generator, of which the following is a specification.

My invention relates to gas-generators, and more particularly togas-machines for making acetylene-gas; and the object is to construct orproduce machines which willbe perfectly automatic in action and whichmay be protected with non-freezing fluids and which are to be providedwith brakes to prevent the water from being thrown in the upper part ofthe machine when the machine is ufied on a railway-train or on a steameror s 1p.

Another advantage is that the machine is made with all the differentparts in a compact inclosure, whereby less pipes are required.

Other objects and advantages will be fully explained in the followingdescription, and the invention will be more particularly pointed out inthe claims.

Reference is had to the accompanying drawings, which form a part of thisapplication and specification.

Figure 1 is a vertical section of the carbidhopper, the generator, thegas-bell, and the surrounding jacket for containing a nonfreezing fluid.Fig. 2 is a horizontal section of the carbid-hopper, taken along theline a; of Fig. 1. Fig. 3 is a broken sectional view showing the meansfor shifting the carbid. Fig. 4 is a perspective view of the casing forthe vertically-operated valve. Fig. 5 is a side elevation of the valvewhich operates in the casing shown in Fig. 4. Fig. 6 is a brokensectional view illustrating the construction of the lower part of thevalve.

Similar characters of reference are used to indicate the same partsthroughout the several views.

This invention is an improvement on the serves to form a seal for thegas-bell. The gas will be collected in the jacket or tank 2 above thenon-freezing fluid. The tank 2 serves also as a means for cooling thegas. The carbid-hopper 7 is carried by the gas-bell 6. A water-brake 8,funnel-shaped, is attached to the upper interior part of the gasbell toprevent the water from being thrown up within the carbid-hopper. ThisWaterbrake is preferably made of porcelain or like material, so that thecarbid will not cling to the waterbrake. A brass casting 9 is attachedto the upper part of the gas-bell, and a brass casting 10 is attached tothe carbidhopper 7. The casting 9 is screwed into the casting 10, andthroat or passage is formed through the casting 9. The feeding. of thecarbid is controlled bya valve 1 1,which is actuated by a plunger-rod12. A casing 13 is mounted in the carbid-hopper to protect the valve 11and permit freedom of movement of said valve. The plunger-rod 12 is notactuated except when the gas-bell falls. Means are provided for theshifting of the carbid in the hopper 7, so that it will be readily fedthrough the neck or discharge from the hopper. The casing 13 has cutoutsin the sides thereof for the passage of carbid. Sheds or shifters 15 areattached to the casing 13, and thus direct the carbid to the sides ofthe casing, so that the carbid will pass through the openings 14. Thevalve 11 carries breakers 16, which cut through the carbid and keep thecarbid from blocking the passage through the casing 13. The breakerskeep the carbid agitated. Slots 17 are formed in the sides of the casing13 for the breakers 16 to move upward and downward. When the gas-bellrises, the valve 11 will cut off the fiow of carbid by coming in contactwith the casting 9, and thus closing the cutouts 14. A pipe18 isattached to the plunger-rod and telescopes on a pipe 19, which serves asa safety-valve for the machine. If thegas-bell should rise high enoughto draw the bottom of the pipe 18 above the water-line, gas would escapethrough the pipe 19 to the atmosphere, .and thus prevent an explosion byan excessive accumulation of gas; If air should accumulate in thegas-bell, it' may be drawn out to some extent through a pipe 20, whichis rovided with a cut-off valve 21. The gas is ighter than air so thatthe air can be drawn out without the loss of much gas. A rod 22 isprovided for agitating the spent carbid on the bottom of thegenerator 1. The rod 22 carries a plurality of stirrers 23. The rod maybe connected to the bottom of the generator 1 by a swivel 24. A waterseal is provided for the rod 22, which consists of the pipe 25, which isattached to the gas-bell 6. The pipe 25 extends far enough below thewater-line to prevent the escape of gas when the gas-bell rises. The rod22 can be agitated only when the gas-bell is down. The spent carbid maybe drawn out through the faucet 26.

A trip for the valve is provided for the valve 11. This trip 27 may beattached to the pi e 19. When the pipe 18 comes far enoug down, it willstrike the trip 27, and thus raise the valve 11 so that carbid will befed to the generator. Gas will be generated and the gas-bell willimmediately rise, so that the valve 11 will cut off the fiow of carbid.A charge of carbid will be obtained every time the bell comes low enoughfor the pipe 18 to strike the trip 27. The pipe 19 may be braced by thesupport 28, which braces from one side, and on the other side by thepipe 29, 'which is itself braced by the bar 30. Gas escapes from thegas-bell by means of the pipe 31, which is bent toward the center of thegas-bell at the top, so that the water-brake 8 will not strike the topof the pipe. Pipe'31 connects with pipe 29, and a pipe 32 connects withthe pipe 29 and extends upward and then downward below the surface ofthe antifreezing fluid in the tank 2. The gas will escape upward throughthis fluid and accumulate in the upper part of the tank 2. The gas foruse is taken from the tank 2 through a pipe 33, which is provided with acut-off valve 34:. The pipe 32 connects with a purifier 35, whichcontains sponges. The purifier 35 is connected to a purifier 36, whichcontains cotton wool. These purifiers dry and strain and purify the gas.

Means are provided for holding the gasbell up when it is desirable thatno gas be generated. Locks 37 are ivoted to the top of the tank 2. Theselocks may be swung upward and made to catch under the rim of thegas-bell.

Various changes may be made in the construction of the machine hereindescribed without de arting from my invention.

Having ully described my invention,what I claim as new, and desire tosecure by Letters Patent, is

1. A gas-machine having a generator, a gas-bell mounted in saidgenerator, a carbidhopper having communication with said gasbell andcarried by said gas-bell, a valve caable of closing said communication,a rod fbr actuating said valve, a blow-ofi pipe extending above thewater-line in said generator and out of said generator and a pipetelescoping on the last-named pipe and attached to said actuating-rod,and a tripping device to arrest the downward motion of said lastnamedpipe.

2.
